Abstract :The estimation of some fuel properties of pork lard biodiesel from its fatty acid methyl ester insert ignore into journalissuearticles values(FAME); composition was investigated. Pork lard biodiesel was produced via transesterification of pork lard and methanol using potassium hydroxide catalyst. The biodiesel was characterized to determine the physico-chemical properties according to American Society for Testing and Materialsinsert ignore into journalissuearticles values(ASTM); methods. The FAME composition of the produced biodiesel was analyzed with Gas chromatography-Mass spectrometer insert ignore into journalissuearticles values(GC-MS);. The values of the fuel properties from the laboratory test using ASTM methods were correlated with that obtained from their calculation from the fatty acid methyl profile and an average absolute deviation insert ignore into journalissuearticles values(AAD); of 4.61, 3.96, 3.10, and 0.78% for iodine value, saponification value, cetane number and higher heating value, respectively were recorded. Methyl oleate insert ignore into journalissuearticles values(C18H34O2); was found to be the dominant ester with percentage composition of 42.6%. The estimated values from FAME profile were found to be very close to the experimental values from ASTM method, hence rigorous laboratory experiments could be mitigated thereby saving cost, time and energy.
